To allwhom it may concern:

Be it known that I, AUGUST WEBER, Sn, a citizen of the United States, residing at Schenec'tady, county of Schenectady, and State of New York, have. invented certain new and useful Improvements in Incandescent-Elem tric-Lamp Sockets, of'which the following-jaa. I ification. I c I v 4 heinvention relates to. such improveno meats; and it consists of the novel construction and combination of parts hereinafter described and subsequently claimed.

Reference may be had to the accompanying drawingsand the reference characters marked thereon, which .form' a part of this specification.-

Similar characters refer to similarparts in the several figures.

Figure 1 of the drawings is a view, partly so 'in side elevation and partly in central vertical section, of a key-socket for incandescent electric lampsembodyingmyinvention. Fig. 2 is a view in side elevation of the same with the cap removed and showing the handle end of the key. Fig. 3 is a view, partly in side elevation and partly in cent'ral vertical'section, of a keyless socket embodying my invention. u a

The principal object of my invention is to provide a simple and efiective automaticallylocking connection between the sleeve and cap of an incandescent-electric-lamp socket. Othsrobjects of the invention willappear in connection with the following description. 3 5 My invention is applicable to various telescopicallyconnecting members, but is especially adapted for use in the'telescopicallyconnecting cap and sleeve members of incandescent-electric-lamp sockets-,and I have illus- 4o trated in the drawings its us'e in such connection."

. In carrying out the principal feature of the I invention the? inner telescoping member is made compressible, and the telescopically connecting members areprovided, in'the man-' ner hereinafter described, with interengaging parts adapted to automatically interlock with a snap action when telescopically applied to each other and to be released by compression 5c of said inner member.

Referring to Figs. 1 and-2 of the drawings,

- 1 is-the sleeve member, and 2 the cap meme"- ing preferably formed of resilient sheet metal.

- teriorly of the screwsccketthrough an apershown.

- her, of the case of a key-socket for incandescen t electric lamps, both of said members he- '5 The case thus formed is adapted to contain T the insulating+base 3, uponwhichi is mounted the screw-socket 4, fixedly connected there with and adapted to receive the screw-threaded shank of an incandescent electric lamp, and the key 5, rotary in the hanger-bearing .6, cperatively connected with .the switchblock 7, adapted to make and break connection between the metal screw-socket 4, which connects with one of the lamp terminals, and, the spring 8, having a connect-i011 (not shown) with one of the circuit wires 9,, the other of the circuit-wires 9 having a connection (not shown) with the spring-armlO, projecting in-,

7o ture 11 in the wall thereof and adapted to contact with the other lampierminal, all in the usual well-knows. manner.

I have not shown in detail the construction of the. switch mechanism nor such parts of the electrical connections as are concealed in the base 3, the manner of constructing and connecting web parts being mail known to those skilled in the art.

.The insulating-base 3 is made to fit loosely within the slecve'l, which is'inade compressible by means of the slot .12, formed in the inner end thereof to receive the shaft of the key 5. 0n ,opposite sides of this slot are. formed projections 14 on the exterior of the sleeve near its inner end, as by slitting the sheet metal at right angles to theslot 12 and forcing outwardly a portion of the metal shell on the inner side ofsuch slit, the projection thus formed terminating abruptly at its outer end at said slit and inclining inwardly therefromtoward the inner end of the sleeve, as

c .The cap 2 is providi with apertures 13, arranged tocorrespond with the position of 95 the projections 14 and adapted to receive 'said projections, respectively, when the parts aretelescopically applied to each other; The sleeve 'beingc'ompressible and saidprojections-beveled or inclined from the inner end 'of5the sleeve toward their outer ends, whereat they terminate abruptly, the cap can be teleseopi cally applied to the slotted end of the and when the apertures 13, in the cap are brought opposite the respective projections'14 on the sleeve the parts will automatically interlock with a snap action. The abruptly-terminating ends of said projections eflfectually prevent accidental separation of the cap from the sleeve; but when it is desired to separate said members it is only nec- .essary to compress the sleeve until said projections are withdrawn from the apertures in i0 the cap. .The connected members themselves 'thus provide the. means whereby they are lockedtogether, dispensing with the use ot 4 screws or other additional parts for that purpose. |5. It desired, the looselyvfitting insulatingbase 8 may be supported within the sleeve by inner end of the sleeve compressible. The,

cap 19 is provided with inward projections 20; inclinedi-nwardly-toward and terminating ab ruptly at their inner ends, whereat the shell is slitted, and adapted to enter apertures 21,

I formed in the sleeve by cutting "and intro-' vertingportions thereot'to form tongues 22,

which enter grooves or recesses 23in the inclosed loosely-fitting insulating-base 24170 assist in supporting the same within the sleeve 5 and to prevent rotative movement between said sleeve andbase when a lamp is being inserted in or removed from the screw-socket 2'5, fixedly connected to said base. The screwsocket-25 and contact-arm 26 are connected with the circuit-wires 9 in the usual manner, I the connections being not shown. The socketsleeve may be provided with a bushing or lining of insnlating'material 27.

What I claim as new, and desire to secure by Letters Patent, is-v Q 1. In a device r the class described, the combination with a pair of members com prising a sheetmetal sleeve having a slotted end and introverted tongues, and a cap adapt ed to telescopically'receive the slotted end of said sleeve, said members having interengaging parts adapted to automatically interi look with a snap action when telescopically applied to each other,-and to be released by compression of said sleeve; of an insulatingbase for electrical fittings loosely inclosed combination with a base of insulating mateand-a sheet-metal cap adapted to telescopicwithin" saidfsleeve inv engagement with said tongues, substantially as described.

2. In a device of the class described, the

rial having a peripheral recess; and an incandescent-lamp support mounted thereon;

of an inclosing case therefor comprising in part a sheet-metal sleeve having a portion of its wallintroverted tooccupy said base-recess, 6

substantially as described.

3. In a device of the class described, the

combination with a base of insulating mate rial having a peripheral recess; and a screwsocket fixedly'mounted thereon; of an inclosing case therefor comprising in part a sheet-metal sleeve having a portion of its wall introverted to occupy said base-recess and prevent a relative vrotative movement between said sleeve, base and socket, substaritially as described.

4. In a device of the class described, and in combination a pair of members comprising a sheet-metal sleeve having a slotted end,

ally receive the slotted end of said sleeve, one of said members being providedyith a recess,:and the other having 9. correspondingly-located transverse slit and the wall on ones'id'e thereof displaced to form a projection beveled or inclined towardsaid recessed member and terminating abruptly at said slit, whereby saidmemb'ers are adapted to automatically interlock with a snap action when telescopically applied to each other,

[and to. lie-released by manual compression of'said slotted sleeve, substantially as described.

I 5'. In a device of the class described, the combination with a compressible sleeve hav- 5 ing portions of its wall cut and introverted to form' tongues; of an insulating-base for electrical fittings loosely inclosed within said sleeve in engagement with said tongues; and acap having inwardly-projecting members adapted. to enter the apertures formed in the sleeve by the introversion of said tongues, whereby said cap and sleeve are locked together and adapted to be released by compression of--.--said sleeve, substantially as de- 105 scribed.
